Anatomy Sensory System

coordinated changes in the lens of the eye that enable one to focus on near and far objects

pigmented middle layer of the ear

coiled portion of the inner ear that contains the organ of hearing

membrane that lines they eyelid and covers the anterior part of the sclera (white if the eye)

The centering of both eyes on the same visual field

clear portion of the sclera that covers the anterior of the eye

sense of taste

lacrimal (tear) gland and is associated ducts

biconves structure of the eye that changes in thickness to accommodate for near and far vision

sense of smell

receptor for hearing located in the cochlea of the internal ear

one of the three small bones of the middle ear: malleus, incus, or stapes

sensory receptor that aids in judging the body position and changes in position; located in the muscles, tendons and joints

bending of the light rays as they pass from one medium to another of a different density

innermost layer of the eye; contains light-sensitive cells (rods and cones)

outermost layer of the eye; made of tough connective tissue; "white" of the eye

bony canal in the internal ear that contains receptors for the sense of dynamic equilibrum; there are three in each ear

gradual loss of sensation when sensory receptors are exposed to continious stimulation

part of the nervous system that detects a stimulus

membrane between the external and middle ear that transmits sound waves to the bones of the middle ear; eardrum

part of the internal ear that contains receptors for the sense of static equilibrum; any space at the entrance to a canal or organ

soft, jellylike substance that fills the eyeball and holds the shape of the eye; vitreous humor
